middle-end/115110 - Fix view_converted_memref_p
view_converted_memref_p was checking the reference type against the
pointer type of the offset operand rather than its pointed-to type
which leads to all refs being subject to view-convert treatment
in get_alias_set causing numerous testsuite fails but with its
new uses from r15-512-g9b7cad5884f21c is also a wrong-code issue.
PR middle-end/115110
* tree-ssa-alias.cc (view_converted_memref_p): Fix.
